大北农获专利，制粒机头尾料可进入专用冷却器

11月6日，大北农（002385）的发明专利《一种制粒机头尾料专用冷却器及方法》获授权，申请号为CN202311718665.1。

制粒开始、收尾或发生打滑时产生的物料需要单独冷却。方案在进料缓冲斗下方连接冷却器腔，上部接收来料，下部负责冷却，中间通过带孔导料板组织物料流动。冷却风进入腔体后，再由缓冲斗两侧的风管排出。把这类零散物料的接收、导入和排风集中在专用设备内，目的是让处理过程能够自动完成。

截至此次授权消息披露时，大北农今年获得的各类专利授权共13项，比上年同期增加44.44%。在2026年上半年，公司研发投入为2.37亿元，同比减少17.19%。企业知识产权记录中，北京大北农科技集团股份有限公司名下可查到806条专利信息和34条著作权信息。
